"We are excited to announce that Antonio Brown will be with the team through at least the 2017 season," Steelers general manager Kevin Colbert said in a statement. "He has played a major role in our success over the past two years and we are thrilled he will be a Steeler for many years to come."

Brown is entering his third season with the Steelers, the team that selected him in the sixth round of the 2010 NFL Draft. He was named the Steelers' MVP last season and was a Pro Bowl honoree as a kick returner. Last season, Brown became the first player in NFL history with at least 1,000 receiving yards and return yards.

Brown was the Steelers' second-leading receiver last season with 69 receptions for 1,108 yards and two touchdowns.
